The last two times that I have memorized an Extended See Invisibility, I was unable to cast it, receiving the error: "No uses or preparations left for that spell." I clearly have two prepared, but they will not cast from a quickslot or the radial menu.

EDIT: I have experienced nothing similar with any other spells, extended or not.

I will give this a try too.

Wow. I am at a loss as to what could be causing this.

I tried it and got the same message. "No uses or preparations left for that spell."

:(

If someone hasn't already tried it, I'll try out that spell in the normal campaign later.

Also, it was working fine up until a few days ago. Just one day, See Invisibility was no longer a functional spell. Which is frustrating for obvious reasons.

I had the same problem with this yesterday. :(

This continues to puzzle me.

I just prepared 4 or 5 ordinary See Invis spells yesterday, could not cast any of them. I was always struck with the message:

[CHAT WINDOW TEXT] [Sat Mar 11 01:49:59] No uses or preparations left for that spell.

((Put the time and crap in there, it's in GMT+1, if it helps you look for the bug))

Arkov, perhaps it was somehow messed up when you made the changes to the "spell focus: divination" feat to allow those who take it to get a longer duration on scrying spells like see invisibility?

I do not have SF: Divination, I have SF: Enchantment.

See Invisibility isn't a scrying spell.
